When you save a room in your heart for him that no one else will ever fill.
When your mind becomes a tape recorder when he's around, and replays all of his words when he's away.
When you can let him have all that you are, and he gives you the same.
When you've built a world together, full of strange streets, plants, animals, mountains. And all of it needs to be explored, enjoyed, savored.
When realizing how deeply happy you are makes you cry.
And you don't mind telling him any of this.
